ground colour, which, at its posterior extremity, bends downward a 

 little, so as to curve in line with the second oblique line of the 

 following segment, which again is in line witli the third oblique line 

 of the next segment, and is continued by the fourth line of the next, 

 which is the pale band below the spiracle and above the lateral flange, 

 which appears inclined upwards at the front of the segment so as to 

 fall into alignment. It might be said that if the upper and lower of 

 these four lines be regarded as Hange lines, faintly bent, then there 

 are only two oblique lines, that is, the two middle ones. 



On October 6th this larva appeared to have detinitely attached 

 itself, as if for pupation, and is now very dark, having passed through 

 a red-brown stage in which the oblique lines were especially conspicuous. 



On the 15th it is noted that this larva had moved several 

 times since the 6th, and had become smaller and perhaps a little 

 darker ; it is now found to have made a nest at the bottom of the tin 

 under a leaf, with enough spinning to be almost entitled to be called a 

 cocoon. This proved, however, to be without any view to immediate 

 pupation, l)ut as a hibernaculum. 



On the 16th another larva is undergoing the same colour changes, 

 the dorsal line is noted as deep red-brown, and the pale yellow-green 

 lines (oblique) are more conspicuous hy a certain amount of red tint 

 along their borders. On the 17th it is darker, the general tone is 

 olive-green, with reddish dorsal line, and oblique lines of the same 

 colour (really the space between the pale oblique lines) crossing 

 several segments and joining the red lateral line. By the 22nd this 

 larva had assumed much the same coloration as the other one. 



The photographs of the larval details (pis. Ill- VI) may be 

 regarded as supplementing those I contributed to Tutt's " British 

 Lepidoptera" (Vol. X, pis. VIII, IX, X), and may be compared 

 with those in the same volume of C. minima, our only other British 

 species of the Everid tribe. 



The larva of E. argiades in its first stage is nearly colourless, 

 with black head and legs. It reaches about 2 mm. in length, when 

 full-fed and stretched out, l)ut is much smaller when first hatched. 



The photograph (pi. Ill) will give some idea of the distribution 

 of hairs and lenticles which conform to the general Lycaenine type. 

 Comparing pi. Ill with pi. XI of Tutt's Br. Lep., Vol. X. the first- 

 stage larva of C. minimd, one might at first glance take the two larvae 

 to be much less alike than they really are : that of minima being from a
